Excluding dust from railroad-cars



UNITED STATES PATENT OFFICE.

JAMES M. COOK, OF TAUNTON, MASSACHUSETTS.

EXCLUDING DUST FROM RAILROAD-CARS.

Specification of Letters Patent No. 9,671, dated April 19, 1853.

T0 all whom t may concern:

Be it known that I, JAMES M. COOK, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful improvement, contrivance, or mode of preventing dust, sparks, or cinders from entering the windows of a carriage when in movement on a railway; and I do hereby declare thatthe same is fully described and represented in the following specification and the accompanying drawings, figures, letters, and references thereof.

Of the said drawings, Figure l denotes an elevation of a part of the side of a carriage to the window openings of which my improvement is `represented as applied. Fig. 2, is a top view of one of my dust guards or deflectors. Fig. 3, is a side view of it. Fig. t, is a cross sect-ion of it.

In the said drawings A, denotes the carriage body of which B, B, B, Sac., are the window openings. To each of these openings, the dust guard or deiector seen at C, O, is applied. It is placed on the outside of a car, and made not only to extend vertically up against the side of the window, but horizontally underneath the window, the vertical part of it being seen at a, while the horizontal part of it is denoted at b. These two parts are rounded at their angle of junction and they are made to project about siX inches from the side of the car.

In the drawings, the deflector is shown as composed of one strip of metal l united at its inner edge to another vertical piece e, whose outer edges f, g, stand at right angles to each ot-her, and are made of equal length. The outer edge of the deflect-or is curved as seen at m, for the purpose of gathering in the air, or rolling it inward and toward the car under it-while the car is in movement in the direction denoted by the arfiector may be secured in place by turned buttons z', or any other suitable contrivance. A simple board or fiat plate placed vertically against the side of a window opening and made t-o stand at an angle of forty-five degrees, or thereabout to the side of a car, and to incline from the direction in which the car is to run, will not effectually prevent t-he entrance of dust or cinders int-o the car window, as there is much of t-he dust that rises upward from the track which cannot be excluded by such a contrivance.

Byymaking the deflector to extend underneath the window as well as upward against its side, we not only greatly increase the deiecting power of it, but we create when the car is in movement plunging currents of air which sweeping downward have a wonderful effect t-o prevent the dust from entering the windows. My invention has been thoroughly tested in practice and has been found to eiectually answer the purpose for which it was intended.

I lay no claim to the application of vertical blinds, shutters, or screens, on the outside of railroad cars and made to stand at angles of about forty-five degrees therewith, and for the purpose of preventing the entrance of dust, smoke or cinders into the windows thereof. But

lVhat I do claim as my invention is- My improvement in the manner of constructing and applying` a deflector to the outside of a railway car, the same consisting not only in making it to extend along the bottom horizontal or lower part, but up along the vertical side of a window opening, substantially as described, and so that while the car is in motion, the air impinged against by the vertical face of the guard will be driven or moved downward and made to pass under or over the guard, so as to prevent the dust thrown directly upward from the track, as well as that moving horizontally or otherwise from entering the windows as described.

In testimony whereof I have hereto set my signature this twenty-ninth day of J anuary, A. D. 1853.

JAS. M. COOK.
